METHOD OF MANUFACTURING WOOLEN ROPING oR suvens. 1

SPECIFICATION forming part of Letters Patent No. 255,195, dated March 21, 1882.

I Application filed May 23, 1881. (No model.)

To all whom it may concern Be it known that we, RICHARD W. ROBIN? soN, of Boston, of the county of Suffolk and State of Massachusetts, and JOHN SHAW, of Dexter, of the county of Penobscot and State of Maine, have invented a new and useful Method of Manufacturing Woolen Roping or Slivers; and we do hereby declare the same to be described in the following specification, reference being bad to the accompanyingdrawings, showing the mechanism used by us in the carrying out of our method or process for the production of the roping or sliver.

The said yarn-roping orcombined sliver is composed of a groundsliver of wool of one color and a series of sections or fillets or sections of a lap or bat of wool of adifi'erent color, the masses of coloring-wool being generally equal, or practically so, in their lengths and at equal, or substantially equal, distances apart on the ground-sliver.

In carrying out our process we divide a lap,

' hat, or sheet of wool of one colorcrosswise or transversely into sections or fillets and lay them, with intervals between them, upon another lap or sheet of fibers of wool of diit'erent color,the sections extendingtransversely across the ground-lap and parallel to each other. After this we separate into strips or slivers of equal widths the groundlap and the coloringsections thereof lengthwise of such ground-lap and crosswise of the coloring-sections, thereby producing the colored sliver.

In the production of such roping or slivers we employ a machine, which we shall now proceed to describe, it being represented inlongitudinal section in Figurelof the accompanying drawings, Fig. 2 being a top view of the cardcylinder Q, hereinafter explained.

In the said drawings the principal operative parts ofa finisher carding-engine are shown with additions thereto necessary to the production of the roping or sliver.

In such Fig. 1, A denotes the main card cylinder; B B, the feed-rolls; (J, the licker-in D, "E, F, and G, the workers and strippers; H, the fancy, and I and K the doffers of a finisher carding-machine, a a and b I) being the sets of rolls for receiving the roping or slivers from the dofl'ers and transmitting them to the spools c c.

With the card we employ an endless apron, M,.fee(1-rollers N N, and a card-cylinder, Q, all arranged as represented, the said cylinder Q having. its card-clothing disposed on it lengthwise isn'parallel strips (1 with intervals (2 between them. i 'Ihe coloring-wool formed in a bat is wound upon a roller, L, having each of its journals resting in a vertical guide, P, as shown at R; This roll of bat is unwound by the action of the feeding-apron and by it carried to the feedrolls N N, by which it is transferred to the card-cylinder Q, from which it is removed in a series of masses, sections, or fillets equal or like in length, the said cylinderQ causing at regular or suitable distances apart the said fillets or sections to be transferred to the teeth of the main card-cylinder A, and upon its charge of wool of adifferentcolor,such charge having been received by it from the feed-rollers B B and the licker-in O. The fancy H lifts the compound charge, or prepares it for removal by the dofi'ers I K. Each sliver or ropin g removed by either of the dofiers will be spotted at intervals with the coloring-wool, and when the sliver or ropingis spun or twisted the resulting yarn will be of two colors, as described.

We are aware of the means described in the United States Patents Nos. 169,139 and 207,272 and the BritishrPatent No. 1,491 for 1872 for spottingortnfting wool and reducingit to roping or slivers, and do not claim such, there being essential diti'erences between them and our invention, which has no reference to the spotting of a lap with tufts or bunches ob- LII strips, and lay such, at intervals apai t, upon a ground-lap, and subsequently divide the latter lengthwise and the coloringfillets thereof crosswise, all as explained, thereby producing slivers not simply tufted, but of a different character, as set forth.

\Ve claim as our invention as follows, viz:

The mode, substantially as described, of male ing slivers composed of wool of one color and wool of a difierent color, such consisting in separating or dividing crosswise of it a lap or hat of wool of one color into sections or fillets, l

and laying them, with intervals between them, and crosswise, upon another or ground sheet or lap of wool of a difi'erent color, and subse- I5 quently separating the whole lengthwise of the said ground-lap into strips or slivers, all being substantially as explained.
